For UK merchants, Q4 is the defining period of the year. Between now and December, retailers will generate up to 35% of annual eCommerce sales (1). In 2024, that translated into nearly £90 billion in UK retail revenue (2).
But opportunity can bring risk. The market is crowded, consumers are selective, and competition for attention has never been fiercer. For many, success will depend not only on products and pricing, but also on promotions, customer experience, and a flawless payments strategy.
Consumer behaviour: discounts drive decisions
Brits are increasingly strategic in their shopping habits. Rather than purchasing impulsively, up to 90% say they have waited for a sale before making a purchase (3). Black Friday is no longer a one-day event but a season, and searches for deals now spike in mid-October according to Google Trends.
This shift causes merchants to rethink their promotional calendars.
Early loyalty discounts and tiered offers throughout November can help spread demand, manage stock more effectively, and build customer trust before the most competitive shopping days. The challenge is clear: balance consumer demand for deals with the need to protect profit margins.
New technologies that drive conversions
Discounting alone is no longer enough. Shoppers look for engaging, personalised experiences that help them buy with confidence.
Research shows that 63% of consumers are more likely to buy from a brand that uses Augmented Reality (AR)(4) and generational data confirms further this trend.
41% of Millennials and 31% of Gen Z say AR influences their buying decisions while 34% of Generation X agree AR increases purchase confidence(5).
From ‘trying on’ clothes virtually to visualising furniture at home, AR helps customers bridge the gap between digital and physical shopping. Retailers that invest now in AR can stand out when consumers are actively looking for assurance.
Payments: a strategic advantage
Many merchants still treat payments as a back-office function but in reality, they can make the difference between a record-breaking Q4 and one defined by missed opportunities.
Take authorisation rates. During Black Friday 2024, some merchants saw performance dip under peak load. On the surface a 1–2% drop in approvals may not sound catastrophic, but at seasonal volumes it can mean millions in lost revenue over a single weekend.
Monitoring authorisations in real time and working with your PSP to adjust routing quickly is essential if you want to hold onto every sale.
Fraud management is another balancing act. Q4 always brings a spike in fraudulent attempts, and merchants have a duty to protect themselves and their customers. Yet rigid rules that decline too many genuine transactions can cost you loyal customers. Combining risk scoring and AI can allow you to block fraudulent transactions while keeping checkout smooth for legitimate buyers.
Finally, for retailers with an international footprint, cross-border payments cannot be overlooked. Local payment methods, multi-currency support and tailored fraud checks will help to ensure foreign customers can complete their purchases without added friction.
Payments are not just a way of moving money from A to B. They are a strategic advantage, and when used well, they can protect margins and build customer trust at the moment competition is fiercest.
Four payment priorities for Q4
To succeed in Q4, UK merchants can focus on four priorities:
Assess infrastructure early. Check your payment setup well before November to make sure no issues are missed. Aim for conversion rates above 98%, as checkout failures during peak sales are costly.
Monitor decline rates in real time. High declines equal lost revenue. Real-time monitoring and fallback routing can save sales that would otherwise fail.
Master the basics. Flexible payment options, simple UX, and fast mobile journeys are now the norm. There are no excuses for clunky checkouts in 2025.
Balance fraud rules. Fraud attempts rise during peak periods. Strong controls are essential, but they must not introduce friction that drives genuine customers to abandon carts.
No margin for error
Q4 offers huge potential but leaves no room for mistakes. Between now and December, nearly £1 in every £3 of annual online sales will be made. Merchants should step into their customers’ shoes to understand where the journey falls short. At the same time, they should monitor decline rates, strengthen fraud prevention, and treat payments as a strategic advantage.
We believe merchants should see their PSPs as partners, not just suppliers. By doing so, they can protect margins and build long-term loyalty well beyond the holiday season.
